DJI launches Ronin 4D – integrated gimbal camera

DJI launches Ronin 4D – integrated gimbal camera

DJI, the world leaders in consumer drones, has launched an integrated camera gimbal calling it the Ronin 4D. It is a completely unique design which integrates a camera with physical gimbal stabilization and focus systems along with wireless transmission. So instead of attaching a camera and lens on a gimbal and taking time to set up for perfect balance, one can simply pick up the integrated Ronin 4D systems and start shooting.

Ronin 4D has Zenmuse X9, which is DJI’s flagship full-frame camera. It also features DJI’s latest image processing system, CineCore 3.0. This system uses DJI’s proprietary chip to provide advanced processor architecture, offering extremely high-performance computing power in a compact cinema camera. CineCore 3.0 allows Ronin 4D to support internal recording of Apple ProRes RAW, ProRes 422 HQ, and H.264 video. It also supports up to 8K/75fps and 4K/120fps video recording, helping deliver multiple options for professional-level creation.

DJI claims that there is 14+ stops of dynamic range. The X9-8K camera has dual native ISO of 800 and 4000 which should give clean shots in low light. The X9-6K camera has dual native ISO of 800 and 5000.

Lidar Range Finder:

There is a Lidar range finder attached which gauges the distance and the attached X9 focus motor helps in getting the focus right.

DJI Ronin 4D makes manual focusing easier than ever. The visualized focus assistance technology displays the ranging points on the main and remote monitors in a simplified top-down view. This provides an innovative and intuitive LiDAR Waveform to locate focus points quickly and allow focus adjustments with extreme precision. Even operators with little or no experience can become adept at manual focusing quickly.

According to DJI the LiDAR Range Finder can cast up to 43,200 ranging points within a 10-meter detection range. [8]Compared with phase detection autofocus (PDAF), Ronin 4D’s LiDAR Focusing System can focus faster, without compromising the image quality or relying on the surface texture of the subject. This is especially useful in low-light environments and results in exceptional focusing capabilities compared to other cinema cameras.

With the new LiDAR Focusing System, Ronin 4D is able to maintain focus even when there is severe motion blur caused by subjects moving quickly. With the focus motor mounted, autofocus is available even on manual lenses. [6] Continuous autofocusing on subjects can be enabled together with ActiveTrack Pro, making it especially convenient for solo operators.



There is an Automated Manual Focus (AMF) mode which gives the operator the accuracy and flexibility of manual focus with the convenience of autofocus. The focus wheel will rotate in sync as the focus point changes, but cinematographers can take manual control at any point. The focus wheel on the right hand grip even features dynamic damping with electromagnetic technology. This gives cinematographers a physical sense of focus changes, providing a more intuitive and modern focusing experience that is unrivaled in the industry today.

Built-in ND Filters:

The X9 camera of DJI Ronin 4D has 9-stop built-in high-quality ND filters (ND 2 to ND 512, or ND 0.3 to ND 2.7) that can be quickly and easily switched thanks to an internal motorized system. These filters were also designed to match and compliment the color science of Ronin 4D.

With the DJI Cinema Color System (DCCS) and robust computing power provided by CineCore 3.0, Zenmuse X9 is able to give images a cinematic look by retaining authentic and accurate colors. It also supports the industry-standard ACES workflow for effortless compatibility with the color tones of other cinema cameras.

DJI Lenses:

X9’s standard DL mount supports three compact full-frame prime lenses. The housings are made of lightweight, monocoque carbon fiber, so each lens weighs just 180 g. More DJI lenses will be available in the future.

Interchangeable mount:

X9 supports interchangeable lens mounts, including DJI’s proprietary DL mount as well as third-party mounts like Leica M. Ultra-wide, f/0.95 large-aperture, electronic zoom, macro, and anamorphic lenses [5]that are compatible with traditional cinema cameras also work on X9, [6] providing flexible lens options.

4-axis Stabilisation:

DJI Ronin 4D adds a Z-Axis to the traditional 3-axis gimbal, which effectively decreases vertical camera shake and offers stabilization performance on par with a dolly. The four axes work together with a downward ToF sensor, forward and downward dual-visual sensors, a built-in IMU and barometer, and an advanced new algorithm to bring the overall stabilization to a whole new level.

Ronin 4D integrates the imaging and stabilization systems while keeping only the sensor and necessary optical components in the gimbal camera. The tilt axis of the gimbal uses dual symmetric motors, whereas both the pan axis and the roll axis are designed with an additional stiffness buffer.



Video Wireless Transmission:

Ronin 4D uses the all-new DJI O3 Pro Video Transmission technology, which offers a 20,000-foot transmission range [10] that would be unimaginable on traditional solutions. In addition to 2.4GHz and 5.8GHz, it supports the DFS frequency band and an AES 256-bit encryption algorithm that can output a 1080p/60fps FHD feed to multiple remote monitors simultaneously with significantly enhanced security, stability, and anti-interference capability.

The 4D Video Transmitter [1] can be directly mounted onto Ronin 4D and powered by the battery of the main body. With a built-in wireless video receiver, the High-Bright Remote Monitor [1] has a 7-inch, 1,500-nit high-bright, wide color gamut touchscreen display that can output both HDMI and SDI signals through the expansion module. [1] Its compact and lightweight body provides optimum portability and efficient setup so users can start shooting immediately.

The High-Bright Remote Monitor supports one transmitter with multiple receivers for video and audio feeds. Two transmission modes are available. The first is Broadcast mode, which sets no limit on the number of receivers and is suitable for monitoring with large crews. The second is Control mode, which supports the coordinated operation of two receivers.

The High-Bright Remote Monitor can connect to the Hand Grips of Ronin 4D, DJI Master Wheels, DJI Force Pro, [11] or the new DJI Three-Channel Follow Focus. [12] This enables remote control of focus and gimbal movements with high precision, starting and stopping of recording, and camera setting adjustments to meet the highest standards of coordinated shooting on sets. In addition, the built-in gyro sensor turns the monitor into a remote motion controller for the gimbal of Ronin 4D.

Mirror Control Mode gives the High-Bright Remote Monitor an identical control interface as the main monitor, including all advanced features such as source clip playback, and camera and gimbal settings, which can now be remotely adjusted even when Ronin 4D is mounted to expansion platforms such as a jib, cable cam, or vehicle mount.

The High-Bright Remote Monitor has a built-in microSD card slot that supports independent recording of video at up to 1080p/60fps. When several remote monitors are used in conjunction, each monitor can play back clips separately without interfering with other monitors.

Storage:

Ronin 4D has a built-in CFexpress Type-B slot along with a USB 3.1 Type-C expansion port for recording directly to an external media disk. [14] It also offers internal recording of the highest-specification videos with DJI PROSSD 1TB, which can be directly connected to a computer via USB-C cable to access media without a traditional SSD reader. These storage choices provide solutions for high cost-effectiveness and to those who want an unrivaled combination of performance and stability.

Sound:

Ronin 4D is equipped with built-in microphones that support dual-channel 24-bit audio recording. It also provides 3.5mm jacks and XLR microphone ports for more audio input solutions.

Battery:

Just like Ronin 2 and Inspire 2, DJI Ronin 4D uses TB50 Intelligent Batteries, which offer up to 2.5 hours of shooting time and can be fully charged in just 1.5 hours. Auto-heating is also supported to enable reliable functionality in severely cold conditions

Price:

The DJI Ronin 4D 4 axis Cinema camera 8k combo kit is priced at $11499.
